Saw blade snaps onto end of extension pole and is used to clear debris (branches, etc.) from view of the camera lens. This enables the camera to focus on desired target and prevents thousands of unwanted pictures. You can remove branches up to 20 feet off of the ground while you are standing below! It is advised to remove all branches from the ground so that it doesn’t give away the location of your camera to others. (Not as shown. New picture to follow).
